构造一个 unsynchronized_pool_resource。

1-4) 用指定的上游内存资源构造一个 unsynchronized_pool_resource 并根据指定的选项调节。结果对象保有 upstream 的副本但不拥有 upstream 所指向的资源。
不接受 opts 参数的重载以默认构造的 pool_options 实例为其选项。不接受 upstream 参数的重载以 std::pmr::get_default_resource() 的返回值为其上游内存资源。

5) 复制构造函数被弃置。

参数

opts	-	含有构造函数选项的 std::pmr::pool_options 结构体
upstream	-	所用的上游内存资源

异常

1-4) 仅若上游资源的 allocate() 函数抛出异常才抛出。这种调用在何种条件下发生或是否发生是未指定的。
